As I have undertaken in this work to satisfy the reader on all points worthy of note concerning the kingdom of Peru, although it will be great trouble to me to stop at one place and return to another, still I shall not fail to do so when it is necessary. In this place I shall treat of the foundation of San Miguel, the first city founded by Christian Spaniards in Peru, and of the valleys and sandy deserts in this great kingdom, leaving the grand road over the mountains once more. I shall fully describe these provinces and valleys on the coast, along which runs another grand road made by the Kings Yncas, of the same magnitude as that in the mountains. I shall give an account of the Yuncas, and of their great edifices, as well as of the information I obtained concerning the secret of its never raining in these valleys and sandy deserts, and of the great abundance of things necessary for the support of man. Having done all this, I shall return to my mountain road, and follow it until I come to the end of this first part. But, before descending to the coast, travelling along the same royal mountain road, we come to the provinces of Calva and Ayavaca, which have the forests of Bracamoros on the east, and the city of San Miguel, of which I shall treat presently, on the west.
